11 Claims. (Cl. 12-672) This invention relates to machines for operating upon boots and shoes and is herein illustrated as embodied in a welt beating machine of the type illustrated in United States Letters Patent No. 1,093,697, granted April 21, 1914, upon an application filed in my name.

Machines of the type referred to have been used extensively in beating out the welts of shoes prior to the operation of attaching the soles thereto. One difficulty which has been experienced in the welt beating operation is that the operator has a tendency to advance the shoe past the beating mechanism too rapidly with the result that the welt is not beaten out to the extent that it should be, particularly around the toe portion of the shoe where, because of the sharp bend which the welt makes at that point the welt may be puckered or otherwise bent out of flattened condition. This has frequently resulted in finished shoes in which the toe portions of the welts thereof are not flat and smooth, or necessitates the repetition of the welt beating operation at the toe portion of the shoe with the consequent loss of time upon the part of the operator.

In view of the foregoing, it is an object of the present invention to provide an improved welt beating machine by which the advance of the shoe past the beating instrumentalities is closely controlled and by which a thorough beating out of the welt is insured. To this end and as illustrated I have provided a welt beating machine comprising a work rest, and means for beating out a welt positioned in engagement with the work rest, together with feed jaws movable laterally of the work rest for advancing the work, one of the feed jaws being adapted to enter the welt crease of the shoe to act as a guide during the feeding operations.

Preferably and as shown, the feed jaws are mounted upon a bracket which is oscillatable laterally of the work rest, one of the jaws being fixed relatively to the bracket and the other of the jaws being movable in a heightwise direction to clamp the work. Preferably too, there is provided a presser foot which is operable to clamp the welt to the work support between feed movements of the jaws, thus insuring that the work is advanced in definite feed steps after operation of the beating instrumentalities has been properly performed. As shown, the presser foot is serrated for the purpose of roughing the welt to prepare it for the reception of cement. also provided a knife operable at the will of the operator to slash the welt, particularly at the toe portion of the shoe, thereby to enable it to be I have beaten out smoothly, there being mechanism operable in response to an initiation of the slashing operation of the knife to render the feed jaws inoperative to feed the work.

These and other features of the invention are 5 disclosed in the accompanying drawings, are set forth in the following detailed specification, and will be pointed out in the claims.

Fig. 13 is a side view in perspective further illustrating the operating instrumentalities upon a shoe.

The invention is illustrated as embodied in a welt beating machine, which as shown in Figs. 1, 2 and 3, 12 and 13, comprises a frame [0 supporting a work rest or guide I2 adapted to enter the welt crease of a shoe I3, a hammer l4 mounted for oscillation relatively to the work rest for beating the inseam l5 and the welt ll of the shoe, a presser foot 16, and work feeding members I8 and 20 for advancing the shoe past the hammer, there being also a knife 22 for producing slashes 23 in the welt when that is considered to be desirable by the operator.

The work rest l2 comprises a plate which has a narrow nose portion 24 adapted to enter the welt crease of a shoe, thereby to hold and guide it in proper operative position relatively to the hammer l4 and the knife 22. The work rest I2 55 is mounted upon a projection 26 on the frame and is secured thereto by a bolt 28 and nut The hammer I comprises a shank portion 32, Figs. 1 6, which is adjustably mounted for heightwise movement in a carrier the shank being prevented from turning in the carrier by means of a key 3-5. The position of the hammer heightwise of the carrier is adjusted by a nut 38 engaging the shank portion 32 and held in adjusted position by a lock nut =36. The hammer is urged resiliently downward by a spring 39 engaging shoulders ll and 43. The hammer has a fiat striking portion 42, Fig. 3, and the side of the hammer in the direction of advancement of the work having a beveled face 4 to facilitate insertion of the work between the hammer and the work support which, as shown, projects laterally beyond the hammer. The hammer is provided with a vertical slot as which intersects the striking face of the hammer and is adapted to receive the presser foot it, the slot being of sufficient size to provide clearance for movement of the presser foot as well as to permit insertion of the knife 22 when the latter is operated.

To provide for oscillation of the hammer relatively to the work rest I2, I mount the hammer carrier upon a rocking lever 58 which has bifurcated end portions carrying a pin 52 upon which the carrier is positioned. The rocking lever has a depending portion 56 mounted upon a shaft and has at its rearward end a split portion 58 slidably engaging a block 65 carried by an eccentric portion (Fig. 9) of a drive shaft E6, the split end portion being held in engagement with the block by means of bolts 66. Upon rotation of the shaft E6 the lever 48 is rocked, thereby to move the hammer I l height- Wise of the work rest.

It is desirable to give a lateral oscillating movement to the hammer in order to smooth down the inseam as well as to press down the welt and to stretch the welt outwardly of the central portions of a shoe. To this end I have provided means for oscillating the hammer carrier forwardly and rearwardly of the machine by means of a lever 68 which has a bifurcated end portion if embracing the eccentric por= tion 62 of the shaft. The lever 08 is pivotally connected at 52 (Figs. 1 and 9) to a bell-crank lever l' l mounted upon the shaft on the frame and having arm i3 pivotally connected at 89 to a link making pivotal connection at 84 with the carrier Thus, by means of the rocking lever 3 and the lever 68 the hammer is moved heightwise of the work rest I2 and is simuitaneously oscillated about the pivot 52 to which the carrier 3 is secured.

The presser foot is is arranged to be oscillated in timed relation to the operation of the hammer and movements of the feed members If? and 26 so that the work will be clamped between the presser foot and the work rest 52 at such times as the hammer is raised and the feed members are inoperative to grip the work. To this end the presser foot is is mounted upon a rocking lever 38 (Figs. 1, 9, 11, i2 and 13), pivoted at 83 on the frame and carrying a stud 95 upon which is positioned a slide block 92 located between the forked ends of a lever 56 mounted upon a shaft 98 carried by a bracket The lever 95 is oscillated by means of a second lever Hi2 mounted upon the shaft and havin a laterally projecting pin lea positioned in a forked portion hi of the lever 93. The lever M32 is normally urged rearwardly of the machine by pressure exerted upon the forked end portion I08 of the lever by a threaded eye bolt IIB (Fig. 4), an end of which is positioned in the fork and secured therein by means of nuts 5 I2 and Washers H4, there being a spring II6 connected to the eye bolt III] and to a second eye bolt II 53 secured to the lever 68. The spring I Iii acting through the eye bolt I I0, lever I02 and lever 96 normally operates to rotate the rocking lever 86 about its pivot 88 in a direction to force the presser foot I6 downwardly toward the work rest I2, thereby to grip the work. Downward movement of the presser foot is limited by means of a stop pin I20 (Fig. 1), mounted upon the bracket I55 and adapted to engage a. tail I22 depending from the lever I02.

For raising the presser foot in time-d relation to the movements of the hammer I4, I have provided a cam I24 (Fig. 11) carried by the lever i l and adapted to engage a roll I26 on a bracket ifs which is secured to the lever I02 by a belt 533. This provides a positive means for raising the presser foot !6 in that the cam I24 when moved to the left with the lever I4 (Fig. 1) engages the roll I25 and operates to rotate the levers I52, 95 and 85 in a direction to raise the presser foot.

In order to enable the presser foot readily to hold the work against movement laterally of the foot I have provided the bottom surface of the presser foot with teeth I32 (Fig. 13), which extend transversely of the line of feed of the work and are adapted to penetrate slightly into the material of the welt of a shoe being operated on. Preferably in order to provide for longitudinal adjustment of the presser foot the latter has a shank portion i34 (Figs. 12 and 13), which is adapted to be positioned in a groove I36 in the lever 86 and to be secured thereto by a bolt I38 passing through an elongated slot 0 in the lever.

The feed members I8 and 20 are arranged for oscillation laterally of the work rest I2 in advancing the work. To this end, they are mounted upon a bracket I42 (Figs. 1 and 2), which is arranged for oscillation about a vertical stud I44 secured to an upstanding portion I45 of the frame. The bracket I42 has a depending arm I46 secured thereto by bolts Ml. The lower end of the bracket has an inturned portion provided with a groove I48 (Fig. 13), adapted to receive a tongue I50 of a lower work feeding member or J'aw I8, the member being held in position of longitudinal adjustment by means of a screw I52. It is to be noted that the upper feed portion of the work feeding member I8 is arranged as indicated at I54 to adapt it to enter the welt crease in feeding a shoe. The Work support I2 is provided with a recess I56 to receive the jaw I 8 in its feeding movements.

The Work feeding member or jaw 20 is carried by a vertical plunger I58 (Fig. l), slida bly mounted in ears 56D forming forward extensions of the bracket I42. The feed member 20 has a laterally extending shank portion I62 secured in a head I64 at the lower end of the plunger I58 and held in position therein by screws I66.

Preferably, the work engaging face of the beating member 2D is provided with serrations I68 to assist the member in clamping the work against the jaw I8 during the work feeding movement. These serrations penetrate the welt during the work feeding movements of the jaws, and operate to roughen the welt to prepare it for the reception of cement. The member 20 is normally forced downwardly toward the work by means of a spring I10 which surrounds the plunger I58, the upper end of the spring bearing against a Washer I12 which operatively engages a lever I14, and the lower end of the spring bearing against a collar I16 on the plunger. The collar I16 is provided with a slotted portion I18 adapted to receive a pin I86 fixed upon the frame for preventing rotational movement of plunger and the member 28. The tension of the spring is adjusted by varying the position of the collar I16 heightwise of the plunger and securing it in position by a screw I82, and lock nut I83.

The mechanism for oscillating the bracket I42 is arranged to be operated in response to rocking movements of the lever 48. Accordingly, the lever 48 is provided with an ear I84 (Figs. 1 and 4) having a bushing I86 on which is located an eccentric pin I88 having mounted thereon a fork- I90 carrying trunnions I62 which support a slide I94 having thereon a vertical roll I96 mounted on a pin I98. The roll is arranged to engage a curved cam slot 286 in a bracket 202 secured to a second bracket 264 mounted on the pivot I44. The bracket 204 has depending portions 206 which embrace a tail 288 on the bracket I42, there being set screws 2 I6 extending through the portions 266 for engaging the tail. By adjusting these screws the angular position of the bracket I42 when at rest can be adjusted. The brackets 202 and 264 are secured together by a tongue and groove connection 2I2 and a screw 2 I4. As the lever 48 is oscillated, the slide I94 is moved in a direction forwardly or rearwardly of themachinewith the result that the roll I96 will vary its position in the cam slot 266 swinging the bracket 262 back and forth in a horizontal plane and we'll produce 2. corresponding movement of the bracket I42 through the connections including the bracket 284 and the depending portions 266. This results in a transverse movement of the feeding members I8 and 20.

The mechanism for operating the feed member 26 in a heightwise direction will now be described. This mechanism comprises a collar 2I6 (Fig. 2), secured to the plunger I58 by means of a screw 2I8 and arranged to be engaged by the forward end of the lever I14 which is operated in time relation to movements of the hammer I4 to raise the plunger positively, the plunger being normally forced downwardly by the spring I10. The lever I14 has a forked end 22!) (Figs. 2, 9 and 11) bearing a pivot 222 upon which is mounted a block 224 having an elongated slot 226 through which the plunger I58 passes. This slot is for the purpose of providing clearance during angular movements of the bracket I42 and the plunger in the feeding of the work. The washer I12 is forced into engagement with the under side of the block by the spring I16 and the block itself is arranged to engage the under side of the collar 2 i 6 at the proper time to raise the plunger.

The lever I14 is operatively connected to and driven by the lever 14. The connections between these levers comprise a sleeve 226 (Figs. 9, 10 and 11) carried at the upper end of the lever 14, a coupling member 238 engaging a pin 23I carried by a stud 232 extending through an opening 234 through the lever 48 and. carried by a lever 235 which is pivotally connected at 238 to a lever 240 which is mounted upon a pivot 242 carried by the frame and upon which also is pivoted the lever I14. The lever I14 has an arm 244 extending rearwardly from the pivot 242 carrying a pin 246 upon which is mounted a latch 248 having a hook 250 at the end thereof which is normally adapted to engage the pivot pin 238 so that the levers I14 and 246 will oscillate together about the pivot 242. To maintain the latch in engagement with the pin 238 there is provided a split collar 252 (Figs. 2 and 7), upon the outer end of the pivot 246 secured thereto by a bolt 253 and having an arm 254 to which is connected a spring 256, the other end of the spring being secured to a projection 258 on the lever I14. The collar 252 carries a member having laterally projecting arms 268 which embrace the lower portion 262 of the lever arm 244 and constitute stops to limit the extent of oscillation of the latch 248. The lever 248 is provided with a contacting portion 264 (Figs. 9, 10 and 11) and the lever arm 244 has a contacting portion 266 which engage each other when the hook 250 is in engagement with the pin 238. In Fig. 2, the latch 248 is shown with its hooked portion in engagement with the pin 238 in which condition the lever I14 will be oscillated periodically causing the feed member 26 to be raised from the work during angular movements of the bracket I42 when the feed member I8 and 28 are moved toward the work rest I2 prior to a feeding operation.

The knife 22 has a laterally curved leg portion 268 (Figs. 5 and 12) and a shank portion 210 which is mounted in a split holder 212 and secured in position by a bolt 214. The holder is carried at the end of a link 216 slidably mounted in a guideway 218 carried by a bracket 266 (Fig. 2), which is adjustably secured to the frame by bolts 282. The link 216 and knife are oscillated by a lever 284 (Figs. 2 and 8), mounted upon a pivot 286 and having at its upper end a guideway 288 receiving a roll 290 mounted upon the rearward end of the link 216. The lever 284 is arranged to be oscillated by a cam 292 having a cam track 294 in which is positioned a roll 298 on the lever 284. The cam is mounted upon a shaft 268 (Figs. 1 and 8), and is driven by a gear 380 from a worm 382 carried by the drive shaft 64, the drive shaft being driven by a pulley 304. The cam 262 is set in operation at the will of the operator by means of a clutch bolt 386 which is arranged to enter a groove 388 and make contact with a projection 309 in the groove upon operation of a starting cam 3) which is carried by an arm 3I2 pivoted at 3I4 and movable downwardly upon depression of a treadle rod 3I6 against the action of a spring 3I8 secured to the arm 3| 2 and to a pin 320 mounted upon the frame. The cam will rotate one revolution after the clutch bolt is released unless the operator holds down the treadle rod. During a single revolution of the cam the knife is caused to make five forward movements which result in the cutting of a single slit in the welt of the shoe being operated upon. During these five movements the hammer will strike five blows and at the end of the slashing operation the knife will be withdrawn during a single return movement. If it is desired to make more than one slash in going around the toe of the shoe the operator may hold down the treadle rod.

When it is desired to cause the knife to produce a slash in the welt it is of course undesirable to feed the work. I have, therefore, provided means for releasing the feed mechanism during the operation of the knife. Accordingly, the link 216 is provided with a projection 322 (Figs. 2 and 12), which has a rod 324 pivoted thereto at 326. The rod carries a spring 328 one end of which engages a fixed collar 336, the other end of which yieldably engages a pin 334 on a lever 336 and presses the pin against retaining nuts 332 on the rod. The lever 336 is mounted upon a pivot 338 and carries a latch 340 (Figs. 2, 10 and 11), having a hooked portion 342 adapted to engage the pin 246 of the lever arm 244. When the link 216 moves forwardly to cause operation of the knife the latch 340 is rotated in a direction to be swung over the pin 246, thus to hold the lever H4 in raised position, the feeding mechanism being disconnected at the time by means of a pin 3M carried by the latch 340 which engages a tail 346 of the latch 248, thereby to rotate it in a counterclockwise direction, as indicated in Fig. 11, with the result that the lever 236 will oscillate without transmitting any motion to the lever H4. At the end of a rotation of the cam 292 as the link 2T8 moves rearwardly, the latch M8 is withdrawn and the spring 256 causes the hook 259 again to engage the pin 238 rendering the feed mechanism again effective to oscillate the lever lid.

It is to be noted that the cam track 294 is provided with dwell such that the lever 283 is not oscillated until after the jaws i8 and 26 have caused three feed movements of the work subsequent to operation of the treadle rod 316. Consequently, if the rod is held down by the operator a single slash 23 will be produced in the work, after which the lever 284 will he returned to its original position, the feed control mechanism will be effective to advance the work three steps, and then the slashing operation will be repeated.

In the operation of the machine a shoe is presented, as shown in Figs. 12 and 13, to the work support l2 with the narrow edge portion 24 thereof engaging the welt crease of a shoe 23 in such manner that the welt i! thereof rests upon the upper face of the work rest, the entrance of the shoe between the work rest and the hammer it being facilitated by the laterally projecting portion of the work rest which guides the work beneath the relieved face of the hammer. The hammer i4 is oscillated by the lever 38 resiliently to deliver blows to the inseam i5 and to the welt and to move outwardly of the shoe across the welt to smooth it out. Between successive harnmer blows the feed jaw 21 engages the welt beneath the hammer and clamps the welt down upon the feed jaw I8. The bracket M2 which carries the feed jaws is swung about its pivot I44 to advance the shoe past the work rest i2 during such time as the hammer i4 and the presser foot l6 are in elevated position. It is to be noted that by having the feed jaws grip the welt close to the operating point, that is, in or adjacent to the paths of movement of the hammer it and the presser foot I6, the shoe can be maintained in engagement with the work support i2 and the jaw l8 by exertion of a comparatively light pressure upon the part of the operator and that the shoe can be turned sharply without releasing it from the control of the feed mechanism. At the end of each feed movement the feed jaw 29 is raised and the jaws are moved back toward the work rest l2, during which time the presser foot I6 is depressed to prevent further advance of the work. This cycle is repeated until the side portions of the shoe are beaten out and the toe portion is approached. When, in the opinion of the operator it is desirable to slash the welt in order that it may lie down more smoothly than would otherwise be the case, operation of the treadle rod 316 initiates an operation of the knife 22 which advances intermittently toward the welt during five revolutions of the main shaft of the machine, the hammer being operated to press down the welt between each partial advance movement of the knife. During this time the feed jaw 20 is held in raised position above the work by means of the latch 340 which holds the lever I'M, which controls the position of the feed jaw, in raised position and the mechanism for oscillating the lever I14 including the latch 250 is disconnected. At the end of the slashing operation the upper end of the lever 284 is moved rearwardly, then the latch 340 is released and the latch 250 again causes the lever H4 to oscillate, thereby causing further feed movements of the work.
